About GXemul's regression tests: |
| 4 |
-------------------------------- |
| 5 |
|
| 6 |
This is a framework for regression testing the emulator. Unfortunately I |
| 7 |
don't have the time or incentive to actually write the individual tests, |
| 8 |
but hopefully this README file should be enough to get someone who wishes |
| 9 |
to write tests started. |
| 10 |
|
| 11 |
The regression tests require a MIPS (cross-)compiler to be available. |
| 12 |
Please study Makefile.skel and ../configure for more information. |
| 13 |
|
| 14 |
Adding a new test is done by writing an assembly language file called |
| 15 |
test_X.S, where X is the name of the test. test_X.good is a file which |
| 16 |
contains the wanted output. |
| 17 |
|
| 18 |
The code in test_common.c calls a function called testmain() in each test |
| 19 |
(which should be written to conform to a 64-bit ABI calling model, and |
| 20 |
return an int value) and prints the return value in hex. If a test wants |
| 21 |
to check more than one int, then it may call printhex() and printstr() |
| 22 |
manually, as long as the output of the program and the contents of |
| 23 |
test_X.good are the same. |
| 24 |
|
| 25 |
|
| 26 |
Here is a list of MIPS instructions; some of them are implemented in the |
| 27 |
emulator, only a few so far have regression tests. NOTE: This list is not |
| 28 |
complete, and probably incorrect in many places. |
